The 3DS demo trend continues with a sneak peek at Mario and Sonic wiping the wrestling mat with one another in the demo for Mario & Sonic at the 2012 London Olympic Games, plus physics, pixels, and platformers, all in this week's Nintendo download.

Isn't it just lovely that we're getting demos for Nintendo 3DS games before the games hit store shelves? Last week's Resident Evil: Revelations demo saw plenty of players dusting off their 3DS for a chance to play the latest entry in Capcom's survival horror series. This week's double-tap of Mario and Sonic (all at once, all for you) should, at the very least, remind players that this game is on the way. I suppose this post does that as well. Nevermind then.

If you're not up for a plumber / hedgehog double team, there's always physics puzzlers Newton Vs. the Horde on WiiWare, or the pixelated platforming goodness of Mutant Mudds on the eShop.

Check out this week's full listing to see if anything strikes your fancy.
